Satellite remote sensing image registration method

Abstract

The invention provides a satellite remote sensing image registration method. The satellite remote sensing image registration method comprises steps that step 1, an earth-fixed coordinate system is established, and coordinates of various regional central points of a first frame of image in the earth-fixed coordinate system are calculated; step 2, the coordinates of the various regional central points of the subsequent various frames of images are calculated; step 3, an integrated image is converted into the earth-fixed coordinate system according to the coordinates of the regional central points in the earth-fixed coordinate system, and the superposed regions of the various frames of images are associated with each other to form the regions after the registration. The above mentioned remote sensing image registration method is used to simulate and calculate an index satisfaction degree of an in-orbit image registration precision, and data is analyzed by comparing with index theory, and therefore the satellite remote sensing image registration method is advantageous in that the in-orbit image registration precision is effectively improved, the index requirement is satisfied, and the precision is guaranteed to be more than 95%.

Description

technical field [0001] The invention belongs to the application field of satellite image processing, in particular to a satellite remote sensing image registration method. Background technique [0002] With the development of technology, the scale of detectors of space-borne cameras of earth remote sensing satellites is increasing day by day, and the data volume of the camera’s in-orbit imaging of the earth increases accordingly, and the requirements for real-time processing on the satellite and on the ground also increase accordingly. Through the registration of continuous multi-frame images, the moving and static targets in the images can be identified. Under the condition of a certain registration accuracy, the trajectory of the moving object in the image can be further predicted, and the trajectory of the moving object is closely related to time. Therefore, the high-precision and fast registration of remote sensing images and its effective implementation are very import...
